IPv6 not working - WAN and LAN Interface getting an IP Adress, not any Client

Gamienator 0

Hello everyone,
first I want to apologize: Not only that I'm not an native english speaker, but second: I still can't unterstand IPv6 completly. Now watching for hours different teaching videos about v6, it's not 100% clear how v6 should be probaly setup.

For my setup: I'm here in Germany and use a Docsis Vodafone connection. The hardware from my provider supports bridge mode and is activated. Now with different Dual-Stack tutorials (which I booked and before applying pfsense worked) I have not the situation, that my WAN and LAN adapter received an v6 Adress, but none of my clients. I'll share you my current settings. It would be really great if some one could help me figure out how to set it up and still use only my internal PiHole as DNS resolver.

In addition, WAN and LAN prefix is different:

Thanks in advance for your help!

Cheers
Gamie

The configuration seems OK, but I don't have Do not wait for a RA selected and you might want to select Do not allow PD/Address release, though that wouldn't affect your problem..

Can you do a packet capture on your LAN, filtering on ICMP6 and on WAN for DHCPv6. The WAN side may be tricky, if you don't have a managed switch configured for port monitoring. You'll want to capture the DHCPv6 sequence. What you could try is to disconnect the WAN cable, boot up pfsense and then plug the cable in, with Packet Capture running. On the LAN side, you're looking for the Router Advertisements and Solicitations. However, those happen frequently and are easy to capture.

@jknott Alright :) Thanks for the answer. Here are the capture of WAN:

Sorry, I guess I wasn't clear enough. I was looking for the capture files, as produced by Packet Capture or Wireshark. I then download and examine them in Wireshark. For example, I can see a router solicitation and advertisement, but I can't see what's actually in the packet. Wireshark will allow me to do that.

Oh sorry, I really thought you need the text only. The Files can be found here: Downloads.zip

Cheers,

I guess you don't have much experience with packet captures. When you do that, you generally specify what you're looking for. For example, I mentioned DHCPv6 on the WAN and ICMP6 on the LAN side. When you use Packet Capture, there are boxes where you say, for example, whether IPv4 or IPv6, protocol and more. Use those to provide only the needed info. For example, most of those 2 captures were IPv4, which is irrelevant to what your problem is. Here's a screen capture of the LAN side, which will capture only ICMP6:

And here is the WAN side. Notice I specified both IPv6 and the port number, though I probably didn't have to specify IPv6, as that port shouldn't be used for anything on IPv4:

It wasn't necessary to specify the addresses in either.

Once you have the capture, you can download it to your computer and post here.

@jknott Heyho,
like you mentioned, WAN can be tricky, the first try was without any captured Packages :(

Here is the LAN Capture: I'll try the WAN capture ASAP

LANCapture.zip

@jknott So I tried this one:

WAN Interface:
IPv6
Port Number 546

got this small package capture. Does this help?

WAN_2.zip

But since this is in an Proxmox with OVS Switch configured, could I capture from that?

One thing I see right off is in the solicit, you're asking for a /60, but being offered a /59. We saw this recently with someone on Comcast, IIRC. On my system, I request and get a /56. I have no idea why you're getting that.

IA Prefix
Option: IA Prefix (26)
Length: 25
Value: ffffffffffffffff3c000000000000000000000000000000…
Preferred lifetime: infinity
Valid lifetime: infinity
Prefix length: 60
Prefix address: ::

IA Prefix
Option: IA Prefix (26)
Length: 25
Value: 000934d100126f513b2a0209084c1239a000000000000000…
Preferred lifetime: 603345
Valid lifetime: 1208145
Prefix length: 59
Prefix address: 2a02:908:4c12:39a0::

On the LAN side, I see your RAs are saying to use a /63, when it should always be a /64. This also happened with that guy on Comcast.

ICMPv6 Option (Prefix information : 2a02:908:4c12:39a0::/63)

Given the same thing is happening with 2 different ISPs, I wonder if there's a bug somewhere.

BTW, you don't have to ZIP the captures. Just download and paste the file is good enough.

@jknott

Here's the Comcast thread, with a similar problem to yours.

Gamienator 0

@jknott Wow ... that is really interesting, especially now, that comcast is not an german based ISP and I got the same issues.

Which now makes me think: Is there a work around that I can reach out via IPv6, is should I even disable it? I'm even fine using NAT until it's sorted out

Gamienator 0

Aehm ... Wow, not I'm just blown away ...

I got now an IPv6 Connection

The "only" thing I changed in pfsense: Set WAN to /59 prefix, DHCPv6-PD to /63 prefix. That is ... Wow ...

Now my last question is: Do I need to setup my pihole with IPv6 too or is it enough to be reachable via IPv4?

JKnott

@gamienator-0

The /59 & /63 prefixes indicate there's still a problem somewhere.

Gamienator 0

@jknott That's true ... Still suprised that I'm now connectable

JKnott

@gamienator-0

My concern is that /63. The LAN side prefix is supposed to be /64 for SLAAC to work properly. I don't know what will happen with the wrong prefix.

Gamienator 0

@jknott Hmm, okay. Well every VM in my network is configured to use SLAAC and working atm

JKnott

@gamienator-0

At the moment, you're using an even number prefix. What happens if you pick an odd one? That /63 moves the boundary between the prefix and suffix over by one to the left. Will a prefix ID 1 now be the same as 0?
